Triethylsilane Chemical Properties,Uses,Production

Referrence

Triethylsilane is a useful versatile reductant since it has a active hydride. It can be used for mediated the palladium-catalyzed dehalogenation reaction of alkyl or aryl halides, the reduction of primary, secondary, and tertiary chlorides, bromides, and iodides catalyzed by iridium, as well as efficient reduction of multiple bonds, azides, imines, and nitro groups, as well as benzyl group and allyl group deprotection. It is also specifically for the hydrosilation of olefins to give alkyl silanes. It is also the catalyst for synthesis of a spiro-oxindole blocker of Nav1.7 for the treatment of pain, redox initiated cationic polymerization and Beckmann rearrangement of cyclododecanone oxime as well as regioselective reductive coupling of enones and allenes.

Uses

Triethylsilane serves as an exemplar for organosilicon hydride behavior as a mild reducing agent. It is frequently chosen as a synthetic reagent because of its availability, convenient physical properties, and economy relative to other organosilicon hydrides which might otherwise be suitable for effecting specific chemical transformations.
This reagent is generally used in these reactions: Hydrosilylations, Silane Alcoholysis, Formation of Singlet Oxygen, Reduction of Acyl Derivatives to Aldehydes, Radical Chain Reductions, Ionic Hydrogenations and Reductive Substitutions(The polar nature of the Si–H bond enables triethylsilane to act as a hydride donor to electron-deficient centers.), Reductive Etherifications and Acetal Reductions, Ether Cleavages, Reductive Couplings and Cyclizations, Aromatic Silylations, Generation of Other Triethylsilyl Reagents, etc.
Related Reagents: Phenylsilane–cesium fluoride; tri-n-butylstannane; tricarbonylchloroiridium–diethyl(methyl) silane–carbon monoxide; triethylsilane–trifluoroacetic acid.

Uses

Triethylsilane is a trialkylsilicon hydride used in the synthesis of alkylsilanes via hydrosilation of olefins. Triethylsilane is also used as an effective reducing agent.

Uses

Triethylsilane is used as a reducing agent inmany organic synthetic reactions.

Fire Hazard

Highly flammable; flash point -4°C (25°F) (Aldrich 1996).
It does not ignite spontaneously in air, but it can explode on heating. The ease of oxidation of this compound is relatively lower than mono- and dialkylsilanes. Reaction with oxidizing substances, however, can be violent. Reaction with boron trichloride could be explosive at room temperature. Even at 78°C ( 108°F), mixing these reagents caused pressure buildup and combustion (Matteson 1990).

Purification Methods

Reflux triethylsilane over molecular sieves, then distil it. It is passed through neutral alumina before use [Randolph & Wrighton J Am Chem Soc 108 3366 1986]. [Beilstein 4 IV 3895.]
